13. Consequências da barragem eclusa do Canal São Gonçalo para a ictiofauna do sistema Patos-Mirim / Consequences of the São Gonçalo channel s dam-lock to the ichthyofauna of the Patos-Mirim system
The present study aimed to investigate the consequences of the São Gonçalo channel dam-lock in the structure of the marine, estuarine and freshwater fish assemblies that inhabit the Patos-Mirim lagoon system. The study area was the São Gonçalo channel that connects the Patos Lagoon with the Mirim Lagoon. Sampling took place monthly during years 2005 (12

14. Avaliação das condições química e física dos sedimentos do estuário Jundiaí-Potengi
The aim of this study was to quantify the presence of major and minor elements in the sediments of the Jundiaí-Potengi estuary, bordering the municipalities of Macaíba, Natal and São Gonçalo do Amarante in the state of Rio Grande do Norte, Brazil, considering the evidence of anthropic activity along this estuary, resulting in pollution by treated and unt

15. Avaliação da qualidade do sedimento do baixo estuário do rio Itajaí-Açu (SC) através de testes de toxicidade crônica
After CONAMA resolution 344 of 2004, environmental agencies have required the quality assessment of the aquatic environments sediments that are subject to remobilization by dredging activities, mainly in port areas. By toxicity tests of embryo-larval development of sea urchin Arbacia lixula, this study analyzed the spatial-temporal quality variation of Itaja

16. Factors structuring fish assemblages in three distinct zones (river, mixture and coastal) of the rio Mambucaba estuary, Angra dos Reis-RJ. / Fatores estruturadores das assembléias de peixes em três distintas zonas (rio, mistura e costeira) do estuário do rio Mambucaba, Angra dos Reis- RJ.
The estuarine systems influence fish assemblages, throughout their longitudinal gradients and remarkable salinity changes. Such assemblages adapt to different habitat constraints and change in spatial and temporal scales. The aim of this study was to assess the ichthyofauna composition and structure in three zones of the Mambucaba estuary (CZ coastal zone; M

17. Caracterização geométrica e parametrização de depósitos transacionais recentes e sua aplicação na modelagem de reservatórios petrolíferos
In this beginning of the XXI century, the Geology moves for new ways that demand a capacity to work with different information and new tools. It is within this context that the analog characterization has important in the prediction and understanding the lateral changes in the geometry and facies distribution. In the present work was developed a methodology

18. Integrated environmental assesment of Santos estuarine system s disposal site and adjancent zones / Diagnostico ambiental integrado da area de influencia do descarte do material dragado do estuario de Santos
The Atlantic Forest coastal plain which surrounds the city of Santos in the State of São Paulo, Brazil, has a great economic importance, principally due to the port of Santos, the largest in Latin America, and the Cubatão industrial complex. The regions estuary has been polluted by multiple contaminant sources for decades, due to industrial, portuary and

19. Zooplankton assemblages from a tidal channel in the Bahía Blanca Estuary, Argentina
Neste estudo pesquisamos pela primeira vez as associações do zooplâncton num pequeno canal de maré, relativamente novo e chamado Bahía del Medio, localizado na região média-exterior do estuário da Bahía Blanca e ao sul do canal principal. Focalizamos o estudo no micro- e mesozooplâncton com ênfase nos grupos Tintinnida, Copepoda e meroplâncton, a

20. Aspects of the time-space variation of the phytoplankton biomass and production and related parameters in Santos Estuary and Bay / Aspectos da variação espacial e temporal da biomassa e produção fitoplanctônica e parâmetros correlatos no estuário e baía de Santos
The relationship between time-space variations of phytoplankton biomass and primary productivity and the variability in physical and chemical characteristics of the water column was investigated by monthly samplings of temperature, salinity, inorganic nutrients, seston and phytoplankton biomass in 4 oceanographic stations in Santos Bay and 3 stations in Sant

21. DinÃmica do microzooplÃncton no Canal de Santa Cruz, Pernambuco, Brasil
Studies were carried out to assess the transport dynamics and the microzooplanktonic community structure from the south and north inlets of Santa Cruz Channel (Itamaracà â PE) in relation to the adjacent shelf, considering tidal phases and depth. Plankton samples were taken with a pump at three stations along a transect across the inlets. At the central st

22. "Experimentos e modelagem numérica com aplicação ao Estuário Tropical do Rio Curimataú, RN" / Experiments and numerical model with application to the tropical estuary of the Catimataú river, RN
The distribution and variability of the termohaline properties and the three-dimensional circulation of the Curimataú river estuary had been studied with the application of the numerical model of simulations Delft3D-Flow, validated with experimental data measured during two consecutive cycles of neap and spring tide. Two numerical grids were applied with th

23. Evolução morfodinâmica da região de influência estuarina do Rio Curimataú/RN, com ênfase nas alternativas do ambiente deposicional de manguezal e a integração de geodados em Sig
The estuaries are important investigation zones of the actual morphodynamic and of depositional facies of recent geological history. They are constituted in important receptor means of the coastal area sediments, where the evolutionary processes occur quickly. They are also attractive means for the development of anthropic activities, which in a disordered w

24. Monitoramento geoambiental do estuário do Rio Paraíba do Norte - PB por meio da cartografia temática digital e de produtos de sensoriamento remoto / Monitoramento geoambiental do estuário do Rio Paraíba do Norte - PB por meio da cartografia temática digital e de produtos de sensoriamento remoto
The North Paraíba River Estuary, located in the eastern portion of the Paraíba State, Northeast Brazil, on coordinates 345000-345730S and 65500-7730W, constitutes a fluvio-marine plain formed by the North Paraíba River and its tributaries Sanhauá, Paroeira, Mandacaru, Tiriri, Tambiá, Ribeira and Guia. This estuary comprises an area of about 260 km2. Inc
